I'm on the opposite side of this with my wife. She can go 5-6 hours after waking up without food. I can... but it feels miserable and like my brain doesn't really start working until I eat. On the flipside, I can eat my last meal of the day and go 7-8 hours without food until I sleep. She can't, though; she'll get severe hunger pangs or be light-headed. So it seems like I should have breakfast + lunch, while she should have lunch + dinner. But being out of sync like that is unbelievably annoying in a relationship where you share / eat the same foods.
